Chance the Rapper surprised everyone at NPR on Monday by showing up for a Tiny Desk Concert. According to the tweets of employees, the performance was announced over the PA system and people immediately leapt from their desks.

One tweet said that he performed three songs (including a Stevie Wonder cover) and read a poem. Another noted that Chance ate a doughnut off of someone's desk before leaving.

All Songs Considered host Bob Boilen wrote on Instagram that the concert will be online in about a week, and based on the reactions from NPR employees, it will be worth the wait. Check out some of their best posts below.
